The efficacy and safety of patent ductus arteriosus stent versus surgical aortopulmonary shunt in the management of babies with duct dependent circulation: a meta-analysis and review of literature

This meta-analysis aims to comprehensively assess the efficacy and safety of both patent ductus arteriosus (PDA) stents and surgical aortopulmonary shunt (APS) as the initial palliative measures in babies relying on ductal-dependent circulation. This review is essential to compare the outcome of relatively newer catheter-based PDA stent procedure with a surgical APS. By synthesizing existing literature, this review aims to provide insights to inform clinical practice and enhance patient care in this challenging clinical scenario. The methodology involved an extensive search of PubMed and Embase databases using specific keywords and terminology related to mortality, procedural outcomes, and postprocedural complications following PDA stent and APS in cyanotic congenital heart defects (CHD) patients. Six retrospective observational studies met the criteria, with 757 patients included. The analysis showed comparable mortality rates between PDA stents and APS. However, PDA stents were associated with decreased risks of mechanical circulatory support, postprocedural complications, and shorter hospital stays, mechanical ventilation, and intensive care unit stays compared to APS. Notably, patients with pulmonary atresia scheduled for biventricular surgery were more prevalent among those receiving PDA stents. In conclusion, while the risk of mortality is similar between PDA stents and APS, PDA stents offer advantages such as shorter hospital stays and reduced complications. Patient characteristics also vary, with a higher prevalence of intact ventricular septum among those receiving PDA stents.

Indications for oropharyngeal biopsy in head and neck squamous cell carcinoma of unknown primary: A systematic review (HNSCCUP).

Patients presenting with head and neck squamous cell carcinoma of unknown primary (HNSCCUP) remain challenging clinical scenarios as large variation exists in practices used to locate the primary. The objective of this systematic review is to review of the literature and offer recommendations for oropharyngeal biopsies in HNSCCUP. Pubmed, Medline and Embase were searched to identify studies from inception to October 2021. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. A total of 483 articles were included and screened, 41 studies met the inclusion criteria, including over 3400 patients from the original articles (122 of these patients were reported on in two sequential articles by a single author - table 1) and 4 large metaanalyses including 1852 patients. The primary site identification rate following random biopsies or deep tissue biopsies is less than 5% in most studies. The mean detection rate following ipsilateral tonsillectomy is 34%; two pooled analyses indicate that the mean detection rate following tongue base mucosectomy is 64%, with this figure rising when the tonsils are negative. High level evidence is lacking, with heterogeneity in the reported studies. Published meta-analyses are based on retrospective data. There is little evidence supporting the practice of random/non-directed oropharyngeal biopsies. Available evidence supports palatine tonsillectomy and tongue base mucosectomy compared to deep tissue biopsies.

DOMPERIDONE VS METOCLOPRAMIDE: COMPARATIVE EVALUATION OF EFFICACY IN TREATING DIABETIC GASTROPARESIS

Diabetic gastroparesis, a common complication of diabetes mellitus, presents a challenging clinical scenario characterised by delayed gastric emptying and symptoms such as nausea, vomiting, abdominal pain, and bloating. Objectives: The primary aim of the study is to compare domperidone vs metoclopramide to evaluate their efficacy in treating diabetic gastroparesis. Methods: This comparative study was conducted in DHQ Hospital Nowshera Khyber Pakhtunkhwa—from June 2022 to June 2023. Data was collected from 190 patients from both genders. Patients meeting the inclusion criteria are randomised into Group A (Domperidone) and Group B (Metoclopramide). The severity of gastroparesis symptoms is assessed using validated symptom-scoring tools before treatment initiation and at regular intervals throughout the study. Results: Data was collected from 190 patients suffering from DM. The mean age of the patients in group A was 52.4 ± 8.2 years and in group B, 53.1 ± 7.5 years. There were 105 female and 185 male patients. The mean duration of DM is 12.3 ± 4.1 years and 11.8 ± 3.8 years in groups A and B, respectively. Group A (Domperidone) and Group B (Metoclopramide) demonstrated significant improvement in symptom scores from baseline to the final assessment. Group A exhibited a substantial reduction in symptom score from 18.2 ± 4.5 at baseline to 8.7 ± 3.2 at the end of the study (p < 0.001), while Group B showed a decrease from 17.9 ± 4.3 to 9.5 ± 3.8 (p < 0.001). Moreover, both groups experienced notable reductions in gastric emptying time. Conclusion: It is concluded that both domperidone and metoclopramide are effective in managing diabetic gastroparesis, with nuances in their safety profiles.

Shoulder arthroplasty outcomes in a series of patients diagnosed with Parkinson’s disease: a retrospective analysis

BackgroundParkinson’s disease (PD) is a neurodegenerative disorder that causes resting tremor and rigidity. Total shoulder arthroplasty (TSA) in patients with PD has proven to be a challenging clinical scenario and is associated with a high risk of complications. The purpose of this study is to explore the relationship between patients diagnosed with PD and outcomes following shoulder arthroplasty (SA). MethodsInstitutional records were queried for patients with PD who underwent SA from 2009 to 2020. Patient medical documentation was retrospectively reviewed to assess demographic information, comorbidity status, preoperative and postoperative range of motion measurements, and complications. Mean ± standard deviation was reported for continuous variables. ResultsA total of 17 patients were identified that met the inclusion criteria. The mean age of the cohort was 57.6 ± 10.6 years at the time of PD diagnosis and 68.1 ± 6.9 years at the time of surgery. The mean follow-up was 1.6 ± 1.2 years. The most common indications for surgery were degenerative joint disease, osteoarthritis, rotator cuff arthropathy, proximal humerus fracture, and rotator cuff tear (1). Mean forward elevation improved from 126.6 ± 24.8° to 131.2 ± 27.8°; mean external rotation improved from 29.4 ± 17.3° to 38.8 ± 10.5°. DiscussionSA is an effective method of improving pain and function in PD patients. Patients undergoing anatomic TSA exhibited the most robust functional improvement in this cohort; however, anatomic TSA was associated with postoperative complications and similar functional measurements were achieved at final follow-up in patients who underwent reverse TSA. Thus, significant care must be taken to ensure the correct implant is chosen on an individual basis to maximize the potential for functional improvement.

Proton Therapy in Non-Rhabdomyosarcoma Soft Tissue Sarcomas of Children and Adolescents.

This paper provides insights into the use of Proton Beam Therapy (PBT) in pediatric patients with non-rhabdomyosarcoma soft tissue sarcomas (NRSTS). NRSTS are a heterogeneous group of rare and aggressive mesenchymal extraskeletal tumors, presenting complex and challenging clinical management scenarios. The overall survival rate for patients with NRSTS is around 70%, but the outcome is strictly related to the presence of various variables, such as the histological subtype, grade of malignancy and tumor stage at diagnosis. Multimodal therapy is typically considered the preferred treatment for high-grade NRSTS. Radiotherapy plays a key role in the treatment of children and adolescents with NRSTS. However, the potential for radiation-induced side effects partially limits its use. Therefore, PBT represents a very suitable therapeutic option for these patients. The unique depth-dose characteristics of protons can be leveraged to minimize doses to healthy tissue significantly, potentially allowing for increased tumor doses and enhanced preservation of surrounding tissues. These benefits suggest that PBT may improve local control while reducing toxicity and improving quality of life. While clear evidence of therapeutic superiority of PBT over other modern photon techniques in NRSTS is still lacking-partly due to the limited data available-PBT can be an excellent treatment option for young patients with these tumors. A dedicated international comprehensive collaborative approach is essential to better define its role within the multidisciplinary management of NRSTS. Shared guidelines for PBT indications-based on the patient's age, estimated outcome, and tumor location-and centralization in high-level referral centers are needed to optimize the use of resources, since access to PBT remains a challenge due to the limited number of available proton therapy facilities.

Abstract Background/Aims The background and aims of this case involve a 70-year-old female patient with a history of complex medical conditions, including bronchiectasis and dementia, who initially presented with respiratory symptoms and fever. The primary aim was to understand the underlying cause of her deteriorating condition, which did not respond to initial antibiotic treatment for suspected pneumonia. Subsequent diagnostic efforts, including extensive vasculitis workup, were undertaken to identify the source of her symptoms, which led to the discovery of positive PR3 results and elevated inflammatory markers. The key goal was to determine the most effective treatment strategy, considering the patient’s unique medical history, balancing the need for immunosuppressive therapy against the potential risks of exacerbating underlying infections. The case ultimately aimed to demonstrate the successful management of the patient’s complex clinical presentation through a multidisciplinary approach, including immunosuppressive therapy and supportive care, resulting in significant improvements in her neurological and functional status. Methods We conducted a comprehensive assessment of a 70-year-old patient with ANCA-associated vasculitis (AAV) involving the central nervous system (CNS) and cutaneous manifestations. Lab tests targeted PR3-positive ANCA, and imaging assessed disease extent. A multidisciplinary team designed a tailored treatment plan with cyclophosphamide, closely monitoring progress. Ethical considerations were adhered to, and a literature review provided context. Data analysis evaluated treatment efficacy, leading to a discussion of lessons learned in managing complex AAV cases. Results We documented the remarkable trajectory of a 70-year-old patient with ANCA-associated vasculitis (AAV) presenting with central nervous system (CNS) involvement and cutaneous manifestations. With a meticulous and tailored treatment plan involving the judicious use of cyclophosphamide, we witnessed a profound recovery marked by significant improvements in both motor and cognitive function. This case underscores the importance of balancing potent immunosuppression with the imperative to curb disease progression and mitigate treatment-associated repercussions in complex AAV presentations. The patient’s restoration to baseline functioning serves as a compelling testament to the potential of precision medicine in managing intricate clinical scenarios of AAV. Our findings emphasize the need for continued awareness and consideration of individualized treatment approaches in similar cases, offering hope and insights for improved outcomes in challenging AAV presentations. Conclusion This case offers valuable lessons on the complexities and challenges involved in diagnosing and managing a multi-faceted condition like AAV. It emphasizes the urgent need for a timely and accurate diagnosis, especially when presented with atypical cases involving the central nervous system and cutaneous manifestations. Moreover, the case enriches our understanding of AAV and contributes insights into its nuanced management. It calls for a sophisticated, patient-centered approach, informed by cutting-edge research, to optimize patient outcomes in this challenging clinical scenario. Disclosure A.J. AlZeera: None. D.

Non-cirrhotic portal hypertension in pregnancy due to schistosomiasis: A case series

The presence of non-cirrhotic portal hypertension in pregnancy poses a challenging clinical scenario as it predisposes women to several life-threatening complications such as variceal haemorrhage, splenic artery aneurysm, pulmonary hypertension and bacterial peritonitis. The haemodynamic changes in pregnancy along with the demands of a growing fetus may worsen the severity of pre-existing non-cirrhotic portal hypertension. In this case series, we discuss four cases of non-cirrhotic portal hypertension in pregnancy in a low to middle income setting and review the literature related to this condition.

Large Skull Metastasis in Follicular Thyroid Carcinoma: A Comprehensive Case Presentation and Systematic Review.

Skull metastases from follicular thyroid carcinoma (FTC) are infrequent but clinically significant, often presenting with localized pain, neurologic deficits, and cranial nerve dysfunction. Early detection and accurate diagnosis pose challenges due to their asymptomatic nature in some cases. A systematic literature review, conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, identified and analyzed 15 relevant studies focusing on large skull metastases in FTC. Data extraction and synthesis included clinical presentation, diagnostic methods, treatment strategies, and patient outcomes. The systematic review encompassed 20 patients with secondary skull metastases from FTC, offering insights into the clinical diversity of this rare condition. Clinical presentations varied, with localized pain (70% of cases) and headaches being predominant symptoms. Imaging techniques, including computed tomography (CT) and magnetic resonance imaging (MRI), played a pivotal role in diagnosis. Surgical resection was considered in select cases, achieving complete or near-complete tumor removal in 30 to 50% of patients. Radiotherapy, including external beam radiation therapy (EBRT) and stereotactic radiosurgery (SRS), provided local control and symptom relief in 70 to 80% of cases. Systemic therapies, such as tyrosine kinase inhibitors (TKIs), showed promise in disease stabilization or regression (45% of patients). Prognosis remained poor, with a median overall survival of 6 to 12 months, reflecting an advanced and aggressive disease state. Managing secondary skull metastases from FTC requires a comprehensive approach, including surgical intervention, radiotherapy, and potential systemic therapies. The rarity of these metastases underscores the need for further research to establish standardized treatment guidelines, explore molecular profiling, and investigate immunotherapy and combination therapies, offering hope for improved outcomes in this challenging clinical scenario.

Comprehensive insights into lumbar epidural varicose veins: Three clinical cases and surgical strategies

ABSTRACT Lumbar epidural varicose veins (LEVs) present a challenging clinical scenario with limited literature. This series addresses the scarcity of comprehensive understanding, emphasizing the need for nuanced exploration. Varied prevalence estimates and clinical oversights underscore the urgency for a standardized approach to surgical interventions. We present three diverse clinical cases: (1) segmental varicose veins causing radicular pain, (2) local varicosities leading to lower paraparesis, and (3) widespread varicose veins with prolonged symptoms. Surgical tactics involved targeted coagulation, crossing of veins, and preservation of collateral blood flow. Advanced imaging techniques guided interventions. Tailoring interventions based on varicose vein subtype, preserving collateral flow, and adopting a staged postoperative approach contribute to successful outcomes. This series provides valuable insights into LEV management, emphasizing the significance of advanced imaging in diagnosis and surgical planning.

Expert Perspectives on Controversies in Metastatic Castration-Resistant Prostate Cancer Management: Narrative Review and Report of the First US Prostate Cancer Conference Part 2.

Management strategies for metastatic castration-resistant prostate cancer (mCRPC) have rapidly shifted in recent years. As novel imaging and therapeutic approaches have made their way to the clinic, providers are encountering increasingly challenging clinical scenarios, with limited guidance from the current literature. The US Prostate Cancer Conference (USPCC) is a multidisciplinary meeting of prostate cancer experts intended to address the many challenges of prostate cancer management. At the first annual USPCC meeting, areas of controversy and consensus were identified during a 2-day meeting that included expert presentations, full-panel discussions, and postdiscussion responses to questions developed by the USPCC cochairs and session moderators. This narrative review covers the USPCC expert discussion and perspectives relevant to mCRPC, including neuroendocrine/aggressive-variant prostate cancer (NEPC/AVPC). Areas of broad agreement identified among USPCC experts include the benefits of poly (ADP-ribose) polymerase (PARP) inhibitors for patients with BRCA1/2 mutations, the use of radioligand therapy in patients with prostate-specific membrane antigen (PSMA)-positive mCRPC, and the need for clinical trials that address real-world clinical questions, including the performance of novel therapies when compared with modern standard-of-care treatment. Ongoing areas of controversy and uncertainty included the appropriateness of PARP inhibitors in patients with non-BRCA1/2 mutations, the optimal definition of PSMA positivity, and systemic therapies for patients with NEPC/AVPC after progression on platinum-based therapies. The first annual USPCC meeting identified several areas of controversy in the management of mCRPC, highlighting the urgent need for clinical trials designed to facilitate treatment selection and sequencing in this heterogeneous disease state.

Approach to Pulmonary Nodules in Connective Tissue Disease.

The assessment of pulmonary nodules is a common and often challenging clinical scenario. This evaluation becomes even more complex in patients with connective tissue diseases (CTDs), as a range of disease-related factors must also be taken into account. These diseases are characterized by immune-mediated chronic inflammation, leading to tissue damage, collagen deposition, and subsequent organ dysfunction. A thorough examination of nodule features in these patients is required, incorporating anatomic and functional information, along with patient demographics, clinical factors, and disease-specific knowledge. This integrated approach is vital for effective risk stratification and precise diagnosis. This review article addresses specific CTD-related factors that should be taken into account when evaluating pulmonary nodules in this patient group.

Anatomic shoulder arthroplasty in patients 40 years or younger

BackgroundGlenohumeral arthritis in adults less than 40 years old represents a challenging clinical scenario to manage. While patients older than 55 have had reproducible success with current shoulder arthroplasty techniques, young patients have historically had less successful outcomes, possibly due to higher physical demands and more complex pathologies. Despite these concerns, anatomic total shoulder arthroplasty (TSA) remains the treatment of choice for young, active patients with severe glenohumeral arthritis and intact rotator cuff. We hypothesize that TSA provides significant relief in pain and functional outcomes in patients less than 40 years old. MethodsWe performed a single-institution retrospective analysis of consecutive patients aged 40 years and younger who underwent TSA between 2007 and 2022. Demographic data included age, sex, body mass index, Charlson comorbidity index, and preoperative diagnosis. Outcome measures included the Single-Assessment Numerical Evaluation (SANE) score, final range of motion, complications, and revision rate. Statistically significant differences between variables were evaluated using a 2-sample t-test at an α level of P < .05. ResultsTwenty-six TSAs were performed in 23 patients with an average final follow-up of 2 years after the procedure. The average age was 33.4 ± 5.3 years with a range of 19-39 years. The most common preoperative diagnosis was osteoarthritis (46%), followed by rheumatoid arthritis (27%) and osteonecrosis/avascular necrosis (19%). The most common glenoid morphology was type B (15) of which 14 were B2 glenoid, followed by type A (11). The SANE score, mean active forward elevation, abduction, external rotation, and internal rotation all improved significantly (P < .05) by the final follow-up. On average, patients in all groups were able to achieve minimal clinically important difference in SANE score after 1 year. There was 1 complication reported of an early postoperative infection treated with irrigation and débridement, and no revision surgeries were performed during the follow-up period. Discussion/ConclusionTSA significantly improved functional outcome measures in patients less than 40 years old with a low rate of complications and revisions in short-term outcomes. As the frequency of TSA continues to increase in adults less than 40 years old, additional studies recording long-term functional outcomes and implant survivorship in this population can be explored.

Abstract 3368: Combination of a chk1/2 dual inhibitor (prexasertib) and gemcitabine reveals a novel intrinsic synergy mechanism in head and neck squamous cell carcinoma

Abstract Head and neck squamous cell carcinoma (HNSCC) presents a challenging clinical scenario due to its recurrence propensity despite existing treatments. Altered intrinsic signaling pathways significantly contribute to therapeutic resistance, demanding exploration of novel strategies to induce tumor cell demise. Dysregulated cell cycle and DNA damage repair constitute pivotal events driving HNSCC progression, offering potential therapeutic targets.CHK1 and CHK2, pivotal regulators of the DNA replication checkpoint, are promising targets in HNSCC. The convergence of DNA-damaging agents with DNA checkpoint inhibitors represents a burgeoning paradigm in cancer management. Our study delves into elucidating the intrinsic signaling mechanisms triggered by the synergistic action of the CHK1/2 dual inhibitor (Prexasertib) and the nucleoside analog (Gemcitabine) in HNSCC.Our study unveiled a robust synergistic effect between Prexasertib and Gemcitabine, inducing substantial cell death in multiple HNSCC cell lines and mouse model. Remarkably, the combination rapidly induced DNA damage and reduced tumor growth in vivo. To unravel the underlying intrinsic signaling mechanism provoked by the Prexasertib/Gemcitabine combination, we conducted comprehensive molecular analyses.Proteomic profiling uncovered distinct alterations in key signaling pathways upon combination treatment. We identified unique overexpression of an embryonic stem cell-specific transcription factor pivotal in genomic stability regulation, solely induced by single-agent Prexasertib. Specifically, the combination therapy showcased unique modulation of critical genes involved in DNA repair, replication, and cell cycle regulation. These alterations included overexpression or suppression of key genes associated with DNA stability and cell proliferation pathways, accompanied by evidence of CHK1/2 inhibition-mediated DNA damage response accompanied by cleavage of CHK-2 and caspase-3 proteins, validated through Western blots.Additionally, functional assays including the colony formation assays demonstrated markedly reduced survival rates with the combination treatment compared to single-agent therapy. Cell cycle analysis revealed a replication catastrophe and increased pH2AX across multiple HNSCC cell lines following combination treatment.Our findings highlight the significance of CHK1/2 inhibition coupled with nucleoside analog-induced DNA damage in unveiling novel intrinsic signaling mechanisms in HNSCC. These insights offer a promising avenue for targeted therapeutic strategies to enhance treatment efficacy and outcomes in HNSCC.This work has been supported by the MGC, FC, P&amp;MC, and BBSR at the H.

A Model to Study Wound Healing Over Exposed Avascular Structures in Rodents With a 3D-Printed Wound Frame.

Soft tissue defects with exposed avascular structures require reconstruction with well-vascularized tissues. Extensive research is ongoing to explore tissue engineered products that provide durable coverage. However, there is a lack of controlled and affordable testbeds in the preclinical setting to reflect this challenging clinical scenario. We aimed to address this gap in the literature and develop a feasible and easily reproducible model in rodents that reflects an avascular structure in the wound bed. We created 20 × 20 mm full thickness wounds on the dorsal skin of Lewis rats and secured 0.5-mm-thick silicone sheets of varying sizes to the wound bed. A 3D-printed wound frame was designed to isolate the wound environment. Skin graft and free flap survival along with exposure of the underlying silicone was assessed. Rats were followed for 4 weeks with weekly dressing changes and photography. Samples were retrieved at the endpoint for tissue viability and histologic analysis. The total wound surface area was constant throughout the duration of the experiment in all groups and the wound frames were well tolerated. The portion of the skin graft without underlying silicone demonstrated integration with the underlying fascia and a histologically intact epidermis. Gradual necrosis of the portion of the skin graft overlying the silicone sheet was observed with varying sizes of the silicone sheet. When the size of the silicone sheet was reduced from 50% of the wound surface area, the portion surviving over the silicone sheet increased at the 4-week timepoint. The free flap provided complete coverage over the silicone sheet. We developed a novel model of rodent wound healing to maintain the same wound size and isolate the wound environment for up to 4 weeks. This model is clinically relevant to a complex wound with an avascular structure in the wound bed. Skin grafts failed to completely cover increasing sizes of the avascular structure, whereas the free flap was able to provide viable coverage. This cost-effective model will establish an easily reproducible platform to evaluate more complex bioengineered wound coverage solutions.

This case study delves into the prevalence of heart failure in patients who not only suffer from Dengue but also concurrently experience fluid leakage syndrome. Through an analysis of clinical data, patient histories, diagnostic criteria, and treatment outcomes, we explore the intricate relationship between these two conditions and their impact on the cardiovascular system. Our findings shed light on the complexities of managing these co-morbid conditions and explore the need for enhanced clinical approaches and awareness in addressing this dual health burden. This case study aims to contribute to the broader understanding of the interplay between Dengue, fluid leakage syndrome, and heart failure, with the ultimate goal of improving patient care and outcomes in such challenging clinical scenarios.

Comparing Doppler Ultrasonography and Computerized Tomography Angiography in Emergency Department Evaluation of Earthquake-Related Crush Injuries: A Case Series Analysis.

This case series aims to provide a comprehensive description of the utilization of doppler ultrasonography (USG) and computerized tomography angiography (CTA) in evaluating patients with earthquake-induced crush injuries in the emergency department (ED). This retrospective case series was conducted on 11 patients who presented with crush injuries following a seismic event. These patients underwent initial assessment using doppler USG, with CTA performed when deemed necessary. Clinical outcomes and diagnostic findings were systematically reviewed. A cohort of 11 earthquake-related crush injury patients (six females, five males; age 3-59 years), predominantly with lower extremity injuries, with entrapped durations that ranged from 12 to 128 hours. Transport centers received patients from both affected regions and nearby provinces. Initial X-rays identified fractures in two cases. Doppler USG and subsequent CTA were employed for vascular evaluation, with CTA confirming doppler USG findings. Of the 11 patients, five exhibited abnormal doppler USG findings. Four patients required dialysis and four underwent amputation surgery. Fasciotomy and debridement procedures were performed in five and seven patients, respectively. Three patients received hyperbaric oxygen therapy (HBOT). Doppler USG emerged as a dependable tool for assessing vascular injuries in earthquake-related crush injuries, offering an effective alternative to CTA without the associated contrast agent risks. These findings underscore the need for further research to establish definitive imaging guidelines in these challenging clinical scenarios.

Revealing Insights: A Comprehensive Overview of Gastric Outlet Obstruction Management, with Special Emphasis on EUS-Guided Gastroenterostomy.

Gastric outlet obstruction (GOO) poses a common and challenging clinical scenario, characterized by mechanical blockage in the pylorus, distal stomach, or duodenum, resulting in symptoms such as nausea, vomiting, abdominal pain, and early satiety. Its diverse etiology encompasses both benign and malignant disorders. The spectrum of current treatment modalities extends from conservative approaches to more invasive interventions, incorporating procedures like surgical gastroenterostomy (SGE), self-expandable metallic stents (SEMSs) placement, and the advanced technique of endoscopic ultrasound-guided gastroenterostomy (EUS-GE). While surgery is favored for longer life expectancy, stents are preferred in malignant gastric outlet stenosis. The novel EUS-GE technique, employing a lumen-apposing self-expandable metal stent (LAMS), combines the immediate efficacy of stents with the enduring benefits of gastroenterostomy. Despite its promising outcomes, EUS-GE is a technically demanding procedure requiring specialized expertise and facilities.

Recurrence in the pelvic side wall after lateral lymph node dissection for rectal cancer.

49 Background: Locally advanced rectal cancer poses a persistent challenge due to the risk of local recurrence, which impacts patient outcomes and quality of life. To address this, lateral pelvic lymph node dissection (LPND) has emerged as a surgical approach to improve local control. However, comprehensive studies evaluating the outcomes and patterns of recurrence after LPND are limited. This retrospective study aimed to fill this gap and provide insights into the effectiveness of LPND. Methods: We conducted a retrospective analysis of 515 patients diagnosed with stage II-III lower rectal cancer who underwent TME and LPND between January 2005 and August 2022. Clinicopathological data were collected, and tumor staging followed the TNM classification system. Recurrence patterns, survival rates, and factors influencing lateral pelvic recurrence were assessed. Results: In our cohort, 18.8% of patients had pathologically positive lateral lymph nodes. Patients with lateral lymph node metastasis exhibited significantly lower 5-year relapse-free survival (31.6%) and overall survival (47.8%) rates compared to those without metastasis (69.5% and 84.7%, respectively). Local recurrence occurred in 20.1% of all patients, with 6.7% experiencing lateral pelvis recurrence (LPR) and 17.4% central pelvis recurrence. Multivariate analysis identified age over 75, lateral lymph node metastasis, and adjuvant chemotherapy as independent risk factors for LPR. Conclusions: Lateral pelvic lymph node dissection remains a valuable tool in managing locally advanced rectal cancer. Our findings underscore the importance of surgeon expertise in performing LPND and the potential benefits of combining treatments to further reduce lateral recurrence. LPND should continue to be explored and refined to enhance patient outcomes in this challenging clinical scenario.
